Toggle switches are a type of switch that consists of a pole, a lever-style actuator, and one to three contact connections. Toggle switches are available in various pole and throw configurations, in both SPST and SPDT configurations. The 1TL1-21E toggle switch is a subminiature single-pole, double-throw (SPDT) switch with a variety of terminals. It features an actuator arm which is pushed up to activate contact and springs back to the original position when released.

1TL1-21E toggle switches are commonly used in a variety of applications. They are typically found in consumer electronics such as home appliances, computer components, and audio/video equipment. They are also frequently used in industrial automation, such as in the control of industrial machinery and process monitoring. 1TL1-21E switch is designed for low-energy applications where minimal power is needed.

The working principle behind a 1TL1-21E toggle switch is based on the movement of an actuator arm. This arm is connected to two contacts--a common and two separate throws. When the actuator is activated by pressing it up, it guides the contact points to make contact with the throws and closes the circuit. When the lever is released, the actuator arm springs back to its original position and breaks the contact in the circuit, thus opening it.

Different from standard toggle switches, the 1TL1-21E has a low-profile actuator and a low-contact force which allows for easy switching of connection and disconnection.1TL1-21E switches also feature a high dielectric strength of up to 750VAC and a contact resistance of less than 50 milliamps.

In conclusion, the 1TL1-21E toggle switch is an ideal choice for applications such as consumer electronics, automation and process monitoring, and industrial control where low-profile and low-power devices are required. It offers reliable connection and disconnection, a low contact resistance of less than 50 milliamps, and a dielectric strength of up to 750VAC.
